Physical properties alkaline earth metals

Commercial Stabilizers. There is a great variety of commercial formulations utilizing the mixture of the alkaU and alkaline-earth metal salts and soaps. In many cases, products are custom formulated to meet the needs of a particular appHcation or customer. The acidic ligands used ia these products vary widely and have dramatic effects on the physical properties of the PVC formulations. The choice of ligands can affect the heat stabiHty, rheology, lubricity, plate-out tendency, clarity, heat sealabiHty, and electrical and mechanical properties of the final products. No single representative formulation can cover the variety of PVC appHcations where these stabilizers are used. [Pg.550]

The auxiliary electrolyte is generally an alkali metal or an alkaline earth metal halide or a mixture of these. Such halides have high decomposition potentials, relatively low vapor pressures at the operating bath temperatures, good electrolytic conductivities, and high solubilities for metal salts, or in other words, for the functional component of the electrolyte that acts as the source of the metal in the electrolytic process. Between the alkali metal halides and the alkaline earth metal halides, the former are preferred because the latter are difficult to obtain in a pure anhydrous state. In situations where a metal oxide is used as the functional electrolyte, fluorides are preferable as auxiliary electrolytes because they have high solubilities for oxide compounds. The physical properties of some of the salts used as electrolytes are given in Table 6.17. [Pg.698]

Some physical and chemical properties of the alkaline earth metals are shown in Table II. It can be seen that beryllium is significantly different from the elements below it in the periodic table in most respects. The fact that the density of beryllium is greater than that of magnesium is perhaps surprising, but can be understood by noting that magnesium is both a more massive and a larger atom. The density of beryllium is to be compared to that of iron (7.9 g cm-3), titanium (4.5 g cm-3), and aluminum (2.7 g cm-3). [Pg.115]

The 3rd group metals a summary of their atomic and physical properties 5.5.5.1 The rare earth metals. A summary of the main atomic and physical properties of the rare earth metals has been collected in Tables 5.11-5.13. To complete the information and the presentation of the entire series of lanthanides the data relevant to Eu and Yb have been included in these tables. However, the same data are reported also in Table 5.7 in comparison with those of the other typical divalent metals (the alkaline earth metals). As for the properties of liquid rare earth metals and alloys see Van Zytveld (1989). [Pg.366]

A remarkable property of the sulphides of the alkaline earth metals and of beryllium and zinc is their power, when certain impurities are present, to exhibit phosphorescence after exposure to bright light. The phenomenon is not due to slow oxidation and is still observable in samples which have been kept hermetically sealed for years it is obvious, therefore, that the effect is a physical one and not analogous to the phosphorescence observable with sulphur (p. 37). The nature and amount of impurity present considerably affect the phosphorescence, chlorides for example causing an increase some impurities inhibit the action.2... [Pg.63]

Research the common physical and chemical properties for each family (a vertical column) in the periodic table. The families to consider are alkali metals, alkaline earth metals, inert gases, halogens, and transition metals. [Pg.50]

A column of the periodic table is called a family. Some families have special names. Group IA elements are called alkali metals, group IIA elements are called alkaline earth metals, group VIIA elements are called halogens, and group VIIIA elements are called the noble gases. The group B elements are called transition elements. Elements with atomic numbers from 58 to 71 are called lanthanides, and elements with atomic numbers from 90 to 103 are called actinides. Families have similar chemical and physical properties. For example, the alkali metals are soft metals at room temperature they are shiny, conduct... [Pg.176]

The transition metals are our premier metals for jewelry making. They have electron configurations that are different from the alkali metals and the alkaline earth metals. Therefore, transition metals exhibit different chemical and physical properties. It is necessary to determine just where electrons reside in transition-metal atoms so we can understand the properties of transition metals and how they bond. To understand these properties and manners of bonding, we must revisit the electron cloud atomic model. [Pg.251]

There are some relationships between a metal s position on the periodic table and the physical properties studied. Magnesium and calcium, alkaline earth metals, are not very malleable or ductile. They have low densities 1.74 g/cm3 and 1.55 g/cm3, respectively. All of the other metals tested are transition metals. They exhibit a wide range of physical properties. Copper and silver are in the same family. They are both quite ductile and malleable. They have fairly high densities. [Pg.277]

Clay minerals and clay colloids are the products of the advanced weathering of primary silicates. They are comprised mainly of silica and alumina, often with appreciable amounts of alkali and alkaline earth metals and iron. Most also have varying amounts of water bound to their surfaces and can take on a variety of different chemical and physical properties depending on the amount of water adsorbed. They have the ability to exchange or bind cations and anions and are capable of complex formation with a wide variety of organic molecules. [Pg.116]

TCs are well documented to bind various metal ions, including alkaline earth metals, Al(ni) and transition metals VO(II), Cr(III), Mn(II), Fe(II/III), Co(II), Ni(II), Cu(II) and Zn(II) . TC can form 2 1 TC-metal complexes with transition metal ions in non-aqueous solution, in which the metal is bound at the 2-amido and 3-enolate chelating sites . TCs are present in plasma mainly in the Ca(II)-bound form or Mg(n)-bound form to a lesser extent, when they are not bound to proteins such as serum albumin. Thus, the bioavailability of TCs should be dependent upon the physical and biochemical properties of their metal complexes instead of their metal-free form. [Pg.613]

The separator column introduced as the Fast-Sep-Cation has similar physical properties. This column was developed primarily for the fast separation of alkali or alkaline-earth metals. In combination with a column switching technique, it is also suitable for the simultaneous analysis of the most important cations of both compound classes (see... [Pg.174]

Radium is classed with the alkaline earth metals with which it properly belongs, although it shows some decided eei inri-ties. It is to be observed that in nearly every cast that member of a family which falls in tin hist series of t he periodic table has certain marked peculiarities, Tin physical properties of the members of this family am shown in Table XII. [Pg.57]

Chapter 10 explains the chemistry and physics that underlie the basic properties of the alkali and the alkaline earth metals. In addition, it presents possible future developments that involve these two families of elements. [Pg.16]

All of the elements in the first 12 groups of the periodic table are referred to as metals. The first two groups of elements on the left-hand side of the table are the alkali metals and the alkaline earth metals. All of the alkali metals are extremely similar to each other in their chemical and physical properties, as, in turn, are all of the alkaline earths to each other. The 10 groups of elements in the middle of the periodic table are transition metals. The similarities in these groups are not as strong as those in the first two groups, but still satisfy the general trend of similar chemical and physical properties. The transition metals in the last row are not found in nature but have been synthesized artificially. The metals that follow the transition metals are called posttransition metals. [Pg.25]
